14 Claims.

My invention relates to machines for the insertion of fastenings, as in the heel-seats of shoes for securing the various elements prior to the attachment of the heels.

In securing the heel-seats of shoes, fastenings, which may consist of pegs of compressed fibrous material or nails, are inserted in varying numbers and positions, the particular design employed depending upon the size of the shoe being oper-.

ated upon. To obtain a close rand-crease, it is desirable that the fastenings shall be driven close to said crease for all the fastening-designs.

An object of my invention is the provision of simple and effective means for arranging fastening-inserting instrumentalities in accordance with the designs for all sizes of shoes, and in all instances in a definite relation to the rand-crease. For the attainment of this object, I utilize a frame upon which a plurality of fastening-inserting sections are movable, preferably one for each different inserting position in all the inserting designs, in passages in which sections may move operating elements or tools, there being a member, as a die-block, having inserting openings which may or may not be less in number than the sections and into co-operation with which the sections may move, said member being provided with means for controlling such co-operation. This control may be exercised by giving certain of the sections access to the die-block-openings, while other sections are retained out of co-operation therewith. As herein illustrated, there are grooves leading from the periphery of the block to recesses, from which the inserting openings extend through the face of the block opposite the grooves and recesses. As disclosed, the openings are from a depression in one face of the die-block, this depression, by its contact with the heel-seat of the shoe operated upon, serving to mold this to a form approximating that of the co-operating end of a heel to be later attached. The blocks are interchangeably mounted upon the frame, each having both openings and grooves arranged according to a particular inserting design. The inserting sections may be provided with projections, which,

before the die-block is seated in its operating position, may move through the grooves into registration with the openings, and, upon seating and latching the block, will be secured against displacement by the presence of the projections in the recesses. With this arrangement, the proper sections, by their entrance into the grooves and recesses, are automatically selected and locked for the insertion of the fastenings corresponding to the design represented by the chosen die-block,

while the sections which are to be inactive are held out of operating position by their contact with the solid periphery of the block. Moreover,

all the active sections have their fastening-passages and operating tools accurately positioned by their engagement with the die-block in a relation as close to the edge of the insole of the shoe being operated on as may be desirable, to insure a tight rand-crease. The manner in which a dieblock is mounted and the operating sections supported and moved, while disclosed in a fragmentary way herein, are the invention of Lester S. Macdonald, being among the features covered by an application filed in his name in the United States Patent Ofiice on October 15, 1931, Serial No. 568,988.

One of the several forms which my invention may assume is illustrated in the accompanying drawing, in which Fig. 1 is a broken perspective view of those portions of a fastening-inserting machine more particularly involved in the invention;

Fig. 2 is a partial top plan view thereof; and

Fig. 3 is a vertical section upon a plane corresponding to that indicated by the line III-III of Fig. 2, but having the fastening-inserting openings and grooves arranged according to a different design. 7

At 10, in Fig. 1, appear fragments of the frame of a fastening-inserting machine, and upon this frame is carried a die-block 12 having a group of openings 14 through which the fastenings are to be driven, and against which the shoe which is to receive said fastenings is forced by pressure mechanism acting upon a jack on which said shoe is supported. The jack and pressure mechanism may be arranged in any one of several well-known ways and are not illustrated. The die-block may be seated for the inserting operation upon a horizontal surface 16 of the frame, being positioned by a spindle 18 depending from its under side and entering a vertical socket 20 in the frame, together with a dowel-pin 22 set in the frame and received by a bore 24 in the block. As will hereinafter appear, the block may be held in a position above its seat for effecting the positioning of the associated mechanisms, but, when finally located for the inserting operation, it is secured against upward displacement by a latch 26 movable by a spring 28 into a bore in the spindle 18. The latch may be withdrawn by a finger-piece 30 to free the block so it may be changed for another. In the upper face of the block, or that toward the jacked work, is preferably formed a depression 32. When the rear portion of the tempered do outsole of a jacked shoe is forced into the depression in preparation for the fastening-inserting operation, said depression acts to mold the heel-seat-surface to substantially the form of the end of a heel thereafter to be attached. This aids in obtaining a close rand-crease. There will be furnished, for use in the machine, die-blocks having their openings 14 respectively arranged according to the several designs corresponding to which the fastenings are to be inserted, the block being changed when a variation in size of the shoes operated upon requires the relation of the openings to be altered. The openings 14 extend from the depression 32 at one face of the die-block to the opposite side thereof, they there terminating in recesses 34, shown as frustoconical, and from which recesses lead outwardly grooves 36 in the opposite face of the die-block, these grooves opening through the periphery of the block.

Surrounding the sides and rear of the dieblock are shown fastening-inserting sections A, there preferably being one of these for each different fastening position in all the designs which are to be employed. The particular form and the manner of mounting these sections is not a part of the present invention. I have shown a primary carrier 40 mounted to slide horizontally in the frame 10 and having, extending toward the die-block and pivoted at 42 to oscillate upon the primary carrier, a secondary carrier 44. At the inner portion of the secondary carrier is an upward projection 46, this and the adjacent supporting portion of the carrier being of such width that it may move through one of the grooves 36 when the die-block is raised from its seat and into registration with the corresponding recess 34. When the die-block is thereafter lowered, the projection is adapted to be received by the recess, within which it fits. Extending upwardly through the projection 46 is a passage 48, with which the corresponding dieblock-opening 14 will be alined, when the projection 46 is within the recess 34, to form a i. fastening-inserting throat. This throat is shown as upwardly and inwardly inclined, to bring the contained fastening into the desired relation to the plate of the last in the shoe being operated upon. There is mounted to reciprocate in each secondary carrier through the passage 48a tool 50, which may serve as a fastening-driver or, by its alternate operation, as both an awl for pricking the heel-seat'and as a driver for inserting the fastening in the pricked hole. Or a separate awl and driver may be arranged upon the carrier for alinement with the passage. Formed upon each primary carrier is a rack 52, with which meshes a pinion 54 upon a vertical shaft 56 journaled in the frame. A torsion-spring 58 acts upon each shaft to urge the corresponding carrier toward the periphery of the die-block 12. The

sections may be withdrawn simultaneously against the force of the springs, with the projections 46 clear of the die-block, by a cam-plate 60 slidable upon the frame. The tools 50, in preparation for the driving stroke, will carry upon their upper extremities, in the passages 48, fastenings supplied in any convenient way.

The apparatus of this invention may be used in the following manner: The operator selects a dieblock having the openings 14 arranged according to the design which will best serve to secure the heel-seats of the particular size of shoes which he has received. With all the sections A forced back by the cam-plate 60 and the latch 26 retracted, the operator applies the chosen die-block, so the spindle 18 and pin 22 enter their openings, but leaving said block so separated from its seat 16 that the section-projections 46 may not only enter grooves 36 in the block but may reach points beneath the recesses 34. With the block thus raised, all the sections are released from the cam-plate and are moved by their springs 58 toward the block. Those sections for which there are no openings 14 are held in inactive positions by their contact with the periphery of the block. Those which are to be used find grooves 36, which they enter and traverse until stopped by the inner extremities of the grooves. The projections of these active sections now register with the block-recesses 34. The operator may thereupon seat the block and secure it by the latch 26. The projections occupy the recesses, and the sections carrying these projections are locked in operating position while theassociated sections are locked out. The openings 14 and the registering die-block-passages 48 of the selected sections form continuous throats, through which the fastenings previously supplied to the passages upon the tools 50 may be driven. The jacked shoe is pressed, for this operation, against the die-block-depression 32, which molds the heel-seat simultaneouslywith the driving of the fastenings. Since only the openings 14 are present in the depression, the grooves 36 being confined to the opposite side of the block, there are not produced, during the molding action, projections from the outsole-surface which would tend to interfere with the proper seating of a heel thereon. The fastening-inserting operations continue in this manner as long as the same design is employed. When it is to be changed, the operator releases the die-block from the latch 26, removes it, moves back all the sections A by means of the cam-plate 60, and supplies another die-block, as just described.
